Brodie Britain Racing (BBR) has created a tuning program for the Mazda MX-5 (2005 and onwards). The Cosworth-based supercharger has been in development for the last 12 months so that it would be fully compatible with all the versions of the third-gen MX-5. Aside from developing the supercharger, BBR has also ditched the Interceptor engine control in favor of a Starchip-developed remap.
The Stage One Kit provided by BBR includes (among other goodies) an intercooler, an Eaton fourth-gen MP62 Supercharger, a replacement air box and high-flow calibrated injectors. The power of the 1.8-liter engine is increased by 93 hp and 53 lb-ft compared to the standard model, for a grand total of 217 hp and a maximum torque of 176 lb-ft.
As for the larger 2.0-liter engine, this one gains an extra 77 hp in the Mk3 and 83 hp in the Mk3.5 versions, along with a 51 lb-ft boost for both models, increasing the total output to 235 hp and 241 hp, respectively. There’s also the Stage Two kit which adds a performance air filter, a new exhaust system and a more aggressive ECU tune. With this kit, the 1.8-liter pumps out 231 hp, followed by the 2.0-liter Mk3 with 252 hp and the Mk3.5 with 258 hp.
The Stage One kit will set you back 4,995 pounds, while the Stage Two costs 6,395 pounds. These prices do not include VAT and are available if fitted at BBR’s factory in UK. If you want the DIY kit, the Stage One costs 4,295 pounds while the Stage Two is 5,455 pounds.
